Pay-per-call employee data API on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to employee data records via the x402 payment protocol. The specific resource `/api/v1/employees/110` returns JSON data for employee ID 110 when a valid USDC micropayment is submitted on the Base network. No API keys or accounts are required — callers attach an X-PAYMENT header with a cryptographic payment proof and receive the response directly.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services. All endpoints on the platform share the same pricing model: $0.02 per request (20,000 base units of USDC, which has 6 decimals). Payment is settled on the Base L2 network to the address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913).
The specific data returned by the employees endpoint is not documented in the crawled material. The platform's documentation pages appear to be behind a wallet-connect gate, so detailed schemas and field descriptions are unavailable. The endpoint accepts POST requests and returns application/json. The x402 challenge was successfully captured, confirming the endpoint is live and accepting payment challenges with a 300-second timeout.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no documented request/response format, and the docs pages are gated behind wallet-connect with no visible content. The purpose of the employees endpoint is only inferrable from the URL path. This is effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available — response format for /api/v1/employees/110 is unknown

- —The employee data endpoint is not listed on the platform's homepage among its advertised APIs, raising questions about whether it is a demo/test resource
